ANALOG DEVICES’ TINY ΜMODULE BOOST REGULATOR FOR LOW VOLTAGE OPTICAL SYSTEMS

Analog Devices, Inc. has announced the Power by Linear LTM4661, a low power step-up µModule regulator in a 6.25mm x 6.25mm x 2.42mm BGA package. Only a few capacitors and one resistor are required to complete the design, and the solution occupies less than 1cm²single-sided or 0.5cm²on double-sided PCBs. The LTM4661 incorporates a switching DC/DC controller, MOSFETs, inductors and supporting components. The ...

Sine Triangle Square Saw Burst Sweep Noise – runs on a PIC16F870

After the recent demise of our multifunction signal generator, we decided to make one of our own.   The circuit uses a PIC16F870 (about $3), an R/2R resistor ladder network (for a real fast and cheap D/A),  and a few other parts. You can check out the schematic and the current source file.  Also the object (hex) file.  All of the sine wave functions utilize a full 256 byte by 8 bit lookup table.  Contrary t ...
